1. A stopover is the shortest distance between two (one-way or two-way) direct flights. Example: PEK-LHR; PEK-LHR-PEK in a direct flight can have a stop point, or may not have a stop point, whether or not there is a stop, only one ticket to take the opportunity. 2. Non-direct flights, also known as connecting flights, refer to the situation where there are intermediate transit points in the flight and multiple tickets need to be connected by air.

Example: PEK-KHI; PEK-KHI-IST 2. round trip (RT) refers to a trip that starts from a point, returns to the original starting point after a certain discount, and uses the flight of air transportation throughout the journey. Example: PEK-NRT-PEK; PEK-KHI (transit)-CAI-KHI (transit)-pek; PEK-KUL (transit)-JKT-MNL (transit)-pek 3. circle trips (CT) refers to a trip that starts from a point and passes through a continuous and annular air route and returns to the original starting point. Example: PEK-HKG-NRT-PEK; PEK-LHR-LIS-MNL-PEK 4. the round world (RTW) refers to a flight that starts from a point, passes (and only passes) the Atlantic Ocean and the Pacific Ocean, and finally returns to the original starting point. Example: PEK-CDG-NYC-PEK 5. Gap trip (Open jaw trip, abbreviated as OJ) refers to the travel from a country, and finally back to the originating country using the general freight range. A. the origin open jaw (ooj) refers to the departure point of the departure journey, which is different from the arrival point of the return journey, that is, both ends of the gap are originating in China. PEK-NRT-PVG B. turnaround open jaw (toJ) refers to the departure point and return point of the trip, but all of them are on the same domestic flight, that is, both ends of the gap are turning back to China. Example: PEK-NRT/OSA-PEK C. A single open jaw (soj) means that the departure point of a trip is different from the arrival point of the return trip, but both are originating in China; in addition, the departure points and return points are also different, but they are all turning back to the domestic flight. Example: PEK-NRT/OSA-PVG
